New technologies for the headquarters:
All buildings construction time reduction by 5% at level 12 and 10% at level 30 for a combined total of 15%.
Buildings take a lot of time to finish after upgrading for some levels, this would speed things up a little. For a 24h building, it would go down to 20h and something. Also there would be a point for upgrading HQ to 30 (or just spending extra crowns).
